Output Azure Function powershell值到azure存储账户

Question

我有一个 powershell 脚本在 azure function 应用程序中运行，该应用程序获取 json IP 列表，解析它并返回一个 IP 列表，每行 1 个。 我需要将这个 output 保存到特定的 azure 存储帐户中。 我正在尝试使用存储帐户中的 static 网站为其他人创建一个 HTTP 端点以检索 IP 列表。

这是脚本

# Input bindings are passed in via param block.
param($Timer)

# Get the current universal time in the default string format.
$currentUTCtime = (Get-Date).ToUniversalTime()

# The 'IsPastDue' property is 'true' when the current function invocation is later than scheduled.
if ($Timer.IsPastDue) {
    Write-Host "PowerShell timer is running late!"
}

# Write an information log with the current time.
Write-Host "PowerShell timer trigger function ran! TIME: $currentUTCtime"

#-------------------------------------------------------------------------------------------

$url = "https://ip-ranges.atlassian.com/"

Invoke-RestMethod $url

$iplist = Invoke-RestMethod $url

$iplist.items | select-object -ExpandProperty cidr

out-file $outputBlob

我已经在 azure 中测试了 function，它在那里运行得很好。 我似乎无法使 function 应用程序的集成输出部分正常工作。 输出的设置是

Binding type - azure blob storage
blob paramter name - outputBlob
Path - test/list.txt
storage account connection - searched and selected the storage account

我没有找到太多关于如何将我的 powershell 脚本 output 添加到此存储帐户的文档。 输出文件显然不起作用。

----------更新代码----------

这是现在成功将文件保存到容器中的代码，但我仍然无法保存到 static 网站的 $web 容器中。 $ 不是我可以在 output 绑定中使用的东西

# Input bindings are passed in via param block.
param($Timer)

# Get the current universal time in the default string format.
$currentUTCtime = (Get-Date).ToUniversalTime()

# The 'IsPastDue' property is 'true' when the current function invocation is later than scheduled.
if ($Timer.IsPastDue) {
    Write-Host "PowerShell timer is running late!"
}

# Write an information log with the current time.
Write-Host "PowerShell timer trigger function ran! TIME: $currentUTCtime"


#------------------------

$url = "https://ip-ranges.atlassian.com/" 

Invoke-RestMethod $url

$call = Invoke-RestMethod $url

$iplist = $call.items | select-object -ExpandProperty cidr

$output = out-string -InputObject $iplist

Push-OutputBinding -Name outputBlob -Value $output

outputBlob 绑定在 integration > outputs > 和 Path 下配置，格式为容器/文件。 我无法指定 $web/file.txt...但如果我指定 web/file.txt，它将创建一个 web 容器并将 output 作为 file.txt 放入其中。 我需要这样做，但它必须在 $web 容器中为 go。

这是我一直想尝试一段时间但实际上并没有抽出时间去做的事情。 当我看到你的问题时决定今天试一试。

因此可以使用 blob output 绑定推送内容，但功能有限。

运行.ps1

using namespace System.Net

# Input bindings are passed in via param block.
param (
    $Request,
    $TriggerMetadata
)

# Call the atlassian API to get the address ranges
$atlassianUri = "https://ip-ranges.atlassian.com/"
$iplist = Invoke-RestMethod $atlassianUri -ErrorAction Stop
$cidrList = $iplist.items | select-object -ExpandProperty cidr

# Push the contents to blob storage using the outputBinding
Push-OutputBinding -Name myOutputBlob -Value $cidrList

# Return a simple response so I know it worked
Push-OutputBinding -Name Response -Value ([HttpResponseContext]@{
    StatusCode = [HttpStatusCode]::OK
    Body = 'Successfully Updated Blob Storage'
})

function.json

您必须在 function 中包含一个计时器输入绑定，但我使用了 HTTP 以便我可以按需触发它以测试它是否有效。

我提供了 static 到 blob output 绑定的路径。 根据这个开放的 GitHub 问题，还不能从 function 中动态分配Path属性。

{
  "bindings": [
    {
      "authLevel": "function",
      "type": "httpTrigger",
      "direction": "in",
      "name": "Request",
      "methods": [
        "get",
        "post"
      ]
    },
    {
      "type": "http",
      "direction": "out",
      "name": "Response"
    },
    {
      "name": "myOutputBlob",
      "type": "blob",
      "path": "functioncopy/ipRanges.txt",
      "connection": "MyStorageConnectionAppSetting",
      "direction": "out"
    }
  ]
}

但是，当将数据发送到存储帐户中的 blob 文件时，上面的代码有效Push-OutputBinding将内容序列化为 JSON 数组，例如

这可能对你有用，也可能不适合你，但我认为没有办法使用 output 绑定来获得原始列表。

但是，您可以在 function 中使用Az.Storage模块，在 function 执行中创建文件并以这种方式上传

运行.ps1

# Variables required - Fill these out
$storageAccountName = '<Insert Storage Account Here'
$containerName = '<Insert StorageContainer Name Here>'
$resourceGroupName = '<Insert resourceGroup Name Here>'
$subscriptionId = '<Insert subscriptionId Here>'

# Call the atlassian API to get the address ranges
$atlassianUri   = "https://ip-ranges.atlassian.com/"
$iplist         = Invoke-RestMethod $atlassianUri -ErrorAction Stop
$cidrList       = $iplist.items | select-object -ExpandProperty cidr

# New-TemporaryFile uses [System.IO.Path]::GetTempPath() location
$tempFile = New-TemporaryFile

# Set the context to the subscription you want to use
# If your functionApp has access to more than one subscription it will load the first subscription by default.
# Possibly a good habit to be explicit about context.
Set-AzContext -Subscription $subscriptionId

# Get the Storage Account Key to authenticate
$storAccKeys = Get-AzStorageAccountKey -ResourceGroupName $resourceGroupName -Name $storageAccountName
$primaryKey = $storAccKeys | Where-Object keyname -eq 'key1' | Select-Object -ExpandProperty value

# Write the CIDR list to the temp file created earlier
$cidrList | Out-File $tempFile

# Create a Storage Context which will be used in the subsequent commands
$storageContext = New-AzStorageContext -StorageAccountName $storageAccountName -StorageAccountKey $primaryKey

# Upload the temp file to blob storage
$setAzStorageBlobContentSplat = @{
    Container  = $containerName
    File       = $tempFile.FullName
    Blob       = 'ipranges.txt'
    Context    = $storageContext
    Properties = @{
        ContentType = 'text/plain'
    }
}

Set-AzStorageBlobContent @setAzStorageBlobContentSplat

# Return a simple response so I know it worked
Push-OutputBinding -Name Response -Value (
    [HttpResponseContext]@{
        StatusCode = [HttpStatusCode]::OK
        Body       = 'Successfully Updated Blob Storage'
    }
)
